Thanks, I might have inadvertently deleted them by clicking reset global options. However, I managed to recreate them, so all good.

Thanks Adrian, That does make sense, however, I have not used projects before. The only two projects I can choose from are the sample project that came with Oxygen and the test project I made. I would expect that my transformations are stored in a default project that is used when you don't explicit...

Just started a first project. Previously I had a number of Transformation Scenarios running, however, they have disappeared.
There seems to be no option to close the project and return to the 'default' settings. How do I get back to those previous transformation scenarios?
